Katherine Jackson is alive and well in Arizona, though she's playing her cards close to her vest.

TMZ broke the story ... Michael Jackson's siblings whisked Katherine away to a spa in Tucson to help her escape what they called the "utter chaos" of the Jackson family home in Encino. Apparently no one told Katherine's nephew, who reported her missing Saturday night.

Now, a photo of Katherine at the Arizona spa has surfaced -- showing her playing UNO with her daughter Rebbie, her granddaughter Stacy, and her great grandson London.

Katherine is supposedly relaxing and having a good time.

Not pictured: MJ's children ... who Katherine abandoned in L.A. during her getaway.
